Antigen: ERBB Receptor Feedback Inhibitor 1 Peptide 1
Background

NCI Identification Number:

00341

Antigen Name:

ERBB Receptor Feedback Inhibitor 1 Peptide 1

CPTC Name:

CPTC-ERRFI1 Peptide 1

Aliases:

ERBB Receptor Feedback Inhibitor 1; MIG-6; Mitogen-Inducible Gene 6 Protein; GENE-33; MIG6; RALT; Receptor-Associated Late Transducer; ERRFI1

Function:

ERRFI1 is a cytoplasmic protein whose expression is upregulated with cell growth (Wick et al., 1995 [PubMed 7641805]). It shares significant homology with the protein product of rat gene-33, which is induced during cell stress and mediates cell signaling (Makkinje et al., 2000 [PubMed 10749885]; Fiorentino et al., 2000 [PubMed 11003669]).ERRFI1 (ERBB Receptor Feedback Inhibitor 1) is a Protein Coding gene. Diseases associated with ERRFI1 include Endometrial Disease and Progesterone Resistance. Among its related pathways are EGF/EGFR Signaling Pathway and Tyrosine Kinases / Adaptors. Gene Ontology (GO) annotations related to this gene include protein kinase binding and kinase binding.Negative regulator of EGFR signaling in skin morphogenesis. Acts as a negative regulator for several EGFR family members, including ERBB2, ERBB3 and ERBB4. Inhibits EGFR catalytic activity by interfering with its dimerization. Inhibits autophosphorylation of EGFR, ERBB2 and ERBB4. Important for normal keratinocyte proliferation and differentiation. Plays a role in modulating the response to steroid hormones in the uterus. Required for normal response to progesterone in the uterus and for fertility. Mediates epithelial estrogen responses in the uterus by regulating ESR1 levels and activation. Important for regulation of endometrium cell proliferation. Important for normal prenatal and perinatal lung development (By similarity).
